The longitudinal section of the inner mold 3 adopts a convex structure design, which helps to improve the strength and durability of the mold, and may also help to improve the demolding efficiency, because the convex structure can better cooperate with the plastic parts and reduce the friction during demolding. Through the optimization of these structures and the increase of the auxiliary demolding mechanism, the mold not only improves the demolding efficiency, but also improves the yield, solving the problem that the simple jacking operation in the prior art cannot achieve rapid separation. The design of this mold takes into account the convenience of operation, the durability of the mold and the quality of the finished product, which is an innovative technology in Bluetooth earphone production.

[0024] Embodiment two

[0025] In order to improve the stability of the device as a whole during demolding, as Figure 2 ,Figure 3 And Figure 4 As shown in FIG. 2, in this embodiment, the top end surface of the support frame 2 is fixedly installed with a jacking cylinder 22 in a circular array, and the inner side of the top end surface of the support frame 2 is in contact with the bottom of the outer mold 1 but not fixedly connected. In the design, the jacking cylinder 22 can be uniformly distributed to provide stable and balanced jacking force, which helps to ensure uniform demolding of the mold. This design also allows the outer mold 1 to be separated from the support frame 2 by the jacking cylinder 22 when needed, increasing the flexibility and convenience of the mold operation, while reducing damage that may be caused by fixed connection.

[0026] Further, the outer diameter of the bottom of the inner mold 3 matches the inner diameter of the hollow inside the support frame 2, and the upper end surface of the inner mold 3 is not in contact with the inner side of the outer mold 1. In the design, the inner mold 3 can move smoothly inside the support frame 2, reducing friction and wear, and improving the service life and operating efficiency of the mold. This design also helps to reduce direct contact between the inner mold 3 and the outer mold 1 during injection molding, reducing wear and damage caused by contact, while also helping to reduce errors during molding.

[0027] Further, the outer wall of the outer mold 1 is fixedly installed with a connecting frame 13 at the top, the inner side of the outer mold 1 is provided with a reserved slot 12 at the top, the reserved slot 12 is provided with an injection pipe 11 at the top, and the outer mold 1 is covered on the top outside of the inner mold 3. In the design, a stable structure is provided for fixing the injection pipe 11, enhancing the overall stability of the mold. This design also allows the injection pipe 11 to be inserted and removed flexibly, facilitating maintenance and replacement, while also ensuring that the molten plastic can be accurately injected into the mold.

[0028] Further, the connecting frame 13 is fixedly connected to the top of the jacking cylinder 22 at the bottom, and the installation position of the connecting frame 13 matches the installation position of the vertical rod 21. In the design, the stability of the jacking cylinder 22 during jacking is ensured, reducing the possibility of failure caused by unstable connection.

In the design, the reverse T-shaped structure design helps to improve the stability of the injection pipe 11 during injection molding, reducing the possibility of leakage or uneven injection caused by unstable structure. At the same time, it ensures the close fit between the injection pipe 11 and the reserved slot 12, improving the accuracy and efficiency of the injection process.

[0030] Further, the servo motor 31 is driven by direct current, and the servo motor 31 is fixedly connected with the vertical rod 21 through the mounting frame 211. In the design, the direct current driving provides stable power output, which helps to improve the response speed and control accuracy of the servo motor 31, thereby improving the operation efficiency of the mold and the quality of the finished product. At the same time, the stability of the servo motor 31 under high load conditions is ensured, the possible faults caused by unstable connection are reduced, and the reliability and durability of the mold are improved.

The vertical rod 21 at the bottom of the support frame 2 is fixedly installed at the corresponding position, so as to ensure the stability of the mounting frame 211 on the vertical rod 21. At the same time, the outer diameter size of the bottom of the inner mold 3 matches the inner diameter size of the hollow inside the support frame 2, so that the inner mold 3 can be movably installed inside the support frame 2. The jacking cylinder 22 fixedly installed on the upper end surface of the support frame 2 is used to make the bottom of the outer mold 1 contact with the upper end surface of the support frame 2, but not fixedly connected, so that the outer mold 1 can be movably installed above the outer mold 13. The liquid injection pipe 11 is movably inserted into the reserved groove 12 at the top inside the outer mold 1, so that the longitudinal section inverted T-shaped structure of the liquid injection pipe 11 matches the inner diameter size of the reserved groove 12, so that the molten plastic can be injected into the mold during the injection molding process. After the inner mold 3 and the outer mold 1 are completely closed, the molten plastic is injected into the mold through the liquid injection pipe 11, and the plastic is cooled and formed in the mold to form a Bluetooth earphone shell. The servo motor 31 driven by the inner mold 3 at the bottom is started, so that the inner mold 3 can perform corresponding actions. The start of the servo motor 31 drives the inner mold 3 to rotate, thereby accelerating the separation of the formed shell from the inner mold or the outer mold 1. Then, the jacking cylinder 22 is started to separate the outer mold 1 from the inner mold 3, and the liquid injection pipe is pressed to accelerate the demolding of the formed shell. After the demolding is completed, the formed Bluetooth earphone shell is taken out. If necessary, other auxiliary tools or mechanical hands can be used to take out the finished product.
